Claude Managed Agents: Build Full AI Agents Without Writing a Single Line of Code

Let Claude Code set up the hosted agent, sandbox, and session for you

Claude Managed Agents

By the end of this guide, you'll have a working Claude Managed Agent — a persistent, hosted AI agent with its own sandboxed environment — running without you hand-writing the agent loop, sandbox config, or API integration yourself. Claude Code's built-in onboarding command walks you through every choice and generates the setup on your behalf.

Who This Is For

  • You want an AI agent that keeps running on its own instead of starting over in a new chat every time

  • You don't want to build and maintain your own agent loop, sandbox, or tool-execution layer from scratch

  • You're comfortable using Claude Code but don't want to hand-write API calls or YAML config files

  • You need a task that runs for minutes or hours with many tool calls, not a single quick reply

  • You want to understand what Anthropic's Managed Agents actually do before using the term in your own content

What You'll Build

A hosted Claude agent running in Anthropic's managed infrastructure that:

  • Runs autonomously in its own secure sandbox, with file access, bash commands, and web search enabled

  • Executes a task you assign through back-and-forth events instead of a single prompt-and-response

  • Keeps its own persistent session, so you can check in, steer it, or interrupt it mid-task

  • Was configured for you through guided questions instead of custom code you maintain

What You'll Need

  • Claude Code installed and signed in

  • A Claude Console account with an active API key

  • A task in mind that actually needs multiple steps or tool calls, not a single question

  • About 10 to 15 minutes for the guided setup
